Inspiring Lectures by Eva Laplace and Matthew Kenworthy at the VVS Weekend

During the fortieth edition of the JVS/VVS weekend in the Duinse Polders, we had the pleasure of attending several fantastic scientific lectures. Prof. dr. Matthew Kenworthy from Leiden University delivered an impressive presentation on exoplanets and exomoons. He demonstrated how his team successfully captured cosmic disks that potentially represent young exoplanets or colliding exomoons. 

On the second day, dr. Eva Laplace took us into the fascinating world of binary stars and their crucial role in supernovae, black holes, and gravitational waves. During a subsequent discussion, she explained how her software TULIPS provides insights into type Ia supernovae and the Hubble tension. Both speakers added extra brilliance to this anniversary weekend and greatly inspired all the amateur astronomers present.

Highlights from the August 12 Solar Eclipse Featured in Magazine Heelal

The November issue of Magazine Heelal prominently features both the collective efforts of VVS Section Helios and my personal journey during the solar eclipse of August 12, 2026.

During the event, VVS Section Helios hosted a public observation at the Maagdentoren in Zichem, welcoming around a hundred visitors to safely view the partial eclipse and promoting upcoming astronomical events. Meanwhile, four members of our section—Walter Swinnen, Johan Reviers, Roger Marien, and Pascal Hilkens—traveled to Spain to experience totality. Observing across locations like Covarrubias, Burgos, Autilla Del Pinto, and Carrion de los Condes, the team captured remarkable footage—including drone imagery of the solar ring—and witnessed 1 minute and 46 seconds of totality.

We are delighted to see these experiences published in Magazine Heelal. You can read the full accounts and view the photographs in the latest November issue.

The 24th Solvay Public Lectures with Nobel Laureates Kip Thorne & David Gross

 

What an absolute privilege to stand face-to-face with true legends of physics this weekend! This past Sunday, during the special public session of the 24th Solvay Lectures at Flagey in Brussels, four of us from Helios astronomy club had the incredible opportunity to attend together—and I even managed to grab selfies with none other than Nobel laureates Kip Thorne and David Gross.

The event was entirely dedicated to gravitational waves and the deepest mysteries of our universe. Kip Thorne—who won the Nobel Prize in 2017 for his decisive contributions to the LIGO detector project and the historic first-ever detection of gravitational waves—delivered a fascinating lecture titled "Probing Black Holes with Gravitational Waves". He brilliantly explained how these ripples in spacetime allow us to uncover the secrets of black holes. Alongside him, theoretical physicist Claudia de Rham took the stage to speak about testing the fundamental nature of gravity, after which David Gross expertly moderated the panel discussion that followed.

Witnessing and meeting these brilliant minds becomes even more awe-inspiring when you realize the groundbreaking work they have accomplished. Kip Thorne earned his Nobel Prize for capturing the very first whispers of spacetime, proving Einstein’s century-old prediction about gravitational waves. David Gross, on the other hand, was awarded the Nobel Prize in Physics back in 2004—alongside Frank Wilczek and David Politzer—for the discovery of asymptotic freedom. Together, they unlocked how the strong nuclear force works and how quarks behave deep inside the smallest building blocks of atomic nuclei.

To cap off an already unforgettable day, we were treated to a lavish, grand reception after the presentations, giving our Helios group the perfect opportunity to raise a glass and process everything we had just experienced. From the subatomic particles that Gross unraveled to the colossal black holes that Thorne and De Rham brought to life, attending this Solvay Conference alongside fellow Helios members is a memory we will cherish for a very long time.

Looking Back at an Unforgettable DDD Day at Urania!

Last week, our astronomical community gathered at Volkssterrenwacht Urania for our traditional DDD (De Duistere Dag) event. With the spectacular Total Solar Eclipse of August 12 still fresh in everyone's memory, the entire day was packed with technical deep-dives, vivid expedition reports, and exciting future plans.

I used this image to talk about the eclipse day itself

Morning Sessions: Tech, Tools, and Expeditions

The day started in classic Urania fashion: catching up with fellow eclipse chasers over hot coffee and viennoiserie in the Urania Bar.

Kris Delcourte officially opened the event with an introduction to the agenda. Maciej Szupiluk followed with a presentation on Total Control, a specialized software tool designed for eclipse photography with Sony cameras. The software was really easy to use and he promissed to have a Nikon version ready, 100 days before next year eclipse.

Ruben Verboven then shared insights and atmospheric data from the Eclipse Weatherstation Project during the August 12 TSE in Spain.

The rest of the morning brought an array of eclipse reports from across Spain and beyond:

Kris Delcourte shared his experiences observing from Montelahorra in the DO Ribera del Duero region.

Wim, Sarah, Marnik, and Karin presented a joint talk on their practical experiences with the Solar Eclipse Workbench. The next release will embed detailed bailey beads.

Roman Weiss rounded out the morning block with a report on the total solar eclipse from Asturias and the total lunar eclipse observed from Andalusia.

Around noon, attendees gathered for a sandwich lunch at the Urania Bar, discussing camera settings, filters, weather predictions, and visual impressions. Before returning to the auditorium for the afternoon sessions, everyone stepped outside for the traditional group photo.

Afternoon Highlights: Iceland, Global Eclipse Chasing, and Drone Imaging

The afternoon session kicked off with invited guest speaker Saevar Helgi Bragason, who brought breathtaking stories of observing the Total Solar Eclipse from Iceland and how he did promote this by his own!!

Werner Hamelinck then offered a comprehensive look at Urania's collective experiences across various observing locations during the August 12 eclipse. Joerg Schoppmeier took the audience on a remarkable global journey, reviewing two partial solar eclipses (New Zealand and Mauritius), two total lunar eclipses (Crete and Joshua Tree National Park), a deep partial lunar eclipse (Madrid), and the total solar eclipse in Spain.

I then had the opportunity to step up and share my own project: Total Solar Eclipse 2026 Wide-Angle Drone Imaging. Operating from Carrión de los Condes, Spain, I used a DJI Neo 2 drone to film the event from the air on August 12, 2026. Capturing the sweeping shadow of totality and the 360-degree horizon twilight from above offered a thrilling new dimension to our eclipse documentation. A live demo was given.
